The world's largest purple flour diamonds were shot 176 million yuan. How did this diamond form?

Recently, an extremely rare Russian purple -pink diamonds were sold for 26.6 million US dollars in Switzerland, or about RMB 176 million. It is reported that the 14.8 carat diamonds are called "the soul of roses" and were shot in the Sotheby's auction house in Geneva, Switzerland. At present, the name of the winner has not been made public.
This diamonds are collected by Russian diamond mining company Alosa. In 2017, Arassa Company adopted a 27.85 -carat rough in the Far East, and then polished it. Russian cutting masters spent a year before making this end diamond to make it oval to ensure its maximum size.
The previously unprocessed diamonds were named Nijinsky to commemorate the Russian Polish ballet actor and choreographer Vaslav Nijinksy.
The 14.8 carat diamonds are called "The Spirit of the Rose". It is the largest of similar diamonds in this auction, because 99%of pink diamonds are lower than 10 carats. Essence
Pin pink diamonds were first discovered in India in the 17th century, and their colors were considered to be a "lattice" or distorted atomic arrangement. According to the Sotheby's website, this is "caused by the high temperature and huge pressure of stones on the earth."
The auction house explained: "This twist removes many carbon atoms from normal positions and changes the quality of the light reflected by diamonds, which causes the diamonds we observe to be pink." Pink diamonds are different from other colors. Diamond, because there is no chemical trace element in its formation process. For example, the existence of nitrogen forms yellow diamonds, and boron forms blue diamonds.
is said to have only 1%pink diamonds greater than 10 carats, and only 4%are rated as the "color diamond" level. The current price record of pink diamonds is maintained by Zhou Dafu's "Pink Star". In April 2017, a 59 -carat diamond Sotheby's auction house was shot at a price of $ 71 million.
. Pink diamonds are the second rare colors in the color diamond family. Only 0.001%of the diamonds mined each year are natural pink diamonds. It has extremely high value.
How is natural diamond? Diamonds are formed on the upper mantle, and the thickest and softest layer of the earth's hard surface layer. It was mostly formed from 3.3 billion to 900 million years ago, far before the occurrence of dinosaurs.
diamond is a form of carbon, and carbon is the fourth element of the solar system. The carbon element is formed as a diamond, which requires a high pressure of 45-60 kite, the high temperature of 900-1300 degrees Celsius, and the depth of 150-200 kilometers, sometimes 660 kilometers deep, located in a mantle transition zone.
This diamonds formed a depths of the earth greater than 150 kilometers, and need to meet many extremely harsh conditions at the same time, so the probability of formation of natural diamonds is extremely low. About 1,000 degrees Celsius high temperatures, which allows carbon atoms to gather to form the right pressure of diamond crystals.
The largest pink drill area in the world is in Australia. Argyle Diamond Mine, located in northwestern Australia, produced 90%of pink diamonds worldwide. Although Agaer produced 90%of the global pink diamonds. However, only 0.1%of the diamonds produced in Agael are pink diamonds every year. Among these pink diamonds, more than half carats (50 points) can only be filled with one palm.

The world's largest purple flour diamonds were taken 176 million yuan. The formation of this diamond was also very difficult. After 3.3 billion years, the surface layer of the earth was at the innermost layer, and it was very high. In the case, a special structure is formed and formed.

Diamonds are formed by the most closely accumulated in the earth under high pressure and high temperature conditions, and the carbon atoms are formed when they are connected by covalent bonds.
